Can stock market bubbles accelerate long term growth? Do such bubbles indicate irrational behavior? This paper studies the effect of innovation uncertainty on the concomitant time path of firm valuations, technology adoption and growth in a setting that incorporates positive network...

It is a triumph of technology and of economics that our computer chips are so universal. Countless applications are only possible because of the staggering variety of calculations that modern chips can compute. But, this was not always the case. Computers used to be specialized, doing only...

This paper studies the effect of innovation uncertainty on the concomitant time path of firm valuations, technology adoption and growth in a setting which incorporates positive network externalities. The resulting stock market bubble, induced by uncertainty and accelerated by the externality...

This paper examines the evolution of firm mark-ups across 26 countries for the period 2001-14. It also discusses and investigates empirically how this can be related to the degree of digital transformation in sectors. Four main facts emerge: i) mark-ups are increasing over the period, on average...

A key feature of Sutton's theory is that industries evolve to distinct market configurations in terms of concentration depending upon whether the markets have a large size, whether the corresponding products are essentially homogeneous, whether they are differentiated by research and development...

We argue that incumbents may be in a position to adapt to radical technological change via interfirm cooperation with new entrants when the incumbents have complementary assets within their firm boundaries that are critical to commercializing the new technology. We study 889 strategic alliances...

A persistent theme in the academic literature on technological innovation is that incumbent enterprises have great difficulty crossing the abyss created by a radical technological innovation. It is argued that incumbents go into decline, while new entrants rise to market dominance by exploiting...

This paper studies the introduction of a new and incompatible technology in a spatial market with network externalities. In competition with an established network the paper investigates how long an entrant optimally should do research before entering the market and what level of product...

We construct a model of industry evolution in which the central force for change is the creation and destruction of submarkets. Firms expand when they are able to exploit new opportunities that arrive in the form of submarkets; they contract and ultimately exit when the submarkets in which they...

In this paper we analyze the dynamics of an R&D differential game allowing for technological spillovers and sigmoid learning functions of multiproduct oligopolies. We demonstrate how the presence of learning together with spillovers may generate a rich set of outcomes, varying from constant...
